A - area of a trapezoid;
a, b - two bases.
A = h * ( a + b ) / 2 / * 2 ( we have to multiply both sides by 2 )
2 A = h *( a + b )
2 A = h a + h b
h b = 2 A - h a
b = ( 2 A - h a ) / h
b = 2 A/h - a
Answer: D )
Yes. An easy way to solve -83+24 is to do 83-24
That equals 59
Your answer is -59
Answer:
The area of the mat is 2/3 m^2
Step-by-step explanation:
Area of a rectangle is length times width or
A = l x w
8/9 x 3/4 =
24/36 =
2/3
Answer:
<em>The correct answer is: False</em>
Step-by-step explanation:
<u>If the sum of the opposite angles in a quadrilateral is 180°</u>, then a circle can be circumscribed about the quadrilateral.
Here, 
but, 
So, a circle can't be circumscribed about the given quadrilateral.
